- UnixUgaDriver.c\r
-\r
-Abstract:\r
-\r
- This file implements the EFI 1.1 Device Driver model requirements for UGA\r
-\r
- UGA is short hand for Universal Graphics Abstraction protocol.\r
-\r
- This file is a verision of UgaIo the uses UnixThunk system calls as an IO \r
- abstraction. For a PCI device UnixIo would be replaced with\r
- a PCI IO abstraction that abstracted a specific PCI device. \r
